When aftershocks are detected, we will update this section.What are aftershocks?Larger earthquakes (above magnitude 5 or so) such as this one are usually followed by smaller ones known as aftershocks that occur in the same area during the days, weeks, months or even years after the main shock.[More info]What about this quake?Based on its magnitude, the fault that was active during the quake likely ruptured beneath a surface area of approximately 3 km2 (1 square miles) as a first-order estimate. The length of the rupture zone thus was probably around 3 km (2 mi).[More info]Recorded aftershocks, latest first (0 quake)Aug 20, 2026 02:31 pm (Universal Time)4 minutes ago4.514 km0 km - This quakeJava, IndonesiaMain Shock (this quake)MoreMap of aftershocksPrevious quakes in the same area of this earthquake4 minutes agoAug 20, 2026 14:31 GMT / Aug 20, 2026 02:31 pm (Universal Time)Lat / Lng: -8.24 / 107.89: Java, IndonesiaSource: BMKGDetail info | You felt it? - Report it!',4.5,45, '#bb202a', 0.9,1.5, '#bb202a', 0.27);map2.addToMap('thisQuake',-8.24,107.89,'4 minutes ago: Mag. 4.5, Java, Indonesia','Earthquake: Mag 4.5 / 14 km (8.7 mi) depth4 minutes agoAug 20, 2026 14:31 GMT / Aug 20, 2026 02:31 pm (Universal Time)Lat / Lng: -8.24 / 107.89: Java, IndonesiaSource: BMKGDetail info | You felt it? - Report it!','default'); // this will be local to this table obj function putQuakeOnMap(id,lat,lon,time,title,html,mag,zIndex) { qTableOlder.putQuakeOnMap(id,lat,lon,time,title,html,mag,zIndex); } map2.circleScale=0.5;qTableOlder.usePalette=1;qTableOlder.startVal=qTableOlder.referenceTime-(80*365.25*86400);qTableOlder.endVal=qTableOlder.referenceTime; qTableOlder.assignMap(map2); (async function(){await new Promise(r => setTimeout(r,4000));map2.map.setZoom(7)})(); })(); (function(){let done=false;async function loadPrevious(){if(done)return;done=true;while(typeof mkRequest=="undefined")await new Promise(r=>setTimeout(r,500));mkRequest("https://server2.allquakes.com/api/getPrevious.php?quakeId=23298288","get","",function(httpObj){let r=httpObj.responseText,d=document;if(""!=r&&200==httpObj.status){let o=JSON.parse(r);if(!o){let s=d.getElementById("olderQuakesSection");if(s)s.remove();return};let table=d.getElementById("qTableOlder");if(!table)return;table.innerHTML+=o.tableRows,qTableOlder.alternateBg();let ph=d.getElementById("placeholder_largestQText");if(ph)ph.innerHTML=o.html;let wrap=d.getElementById("sectionPreviousCWrap");if(wrap)wrap.style.display="";eval(o.js)}})}let d=document,target=d.getElementById("sectionPreviousCWrap")||d.getElementById("placeholder_largestQText")||d.getElementById("qTableOlder");if(!target||!("IntersectionObserver" in window)){loadPrevious();return}let obs=new IntersectionObserver(function(entries){if(entries.some(e=>e.isIntersecting)){obs.disconnect();loadPrevious()}},{rootMargin:"300px 0px"});obs.observe(target)})();]]>
